Problems solved by technology

For the current motor, when the motor has high-frequency electromagnetic resonance and the electromagnetic noise is too high, it is necessary to disassemble the motor, redesign the electromagnetic scheme of the motor to change the electromagnetic frequency of the electromagnetic rotational force wave, and replace the motor with a different number of slots. The rotor is used to reduce the noise of the motor, and the processing process is complicated

Abstract

The present invention provides a motor and a method for controlling the motor for noise reduction. The motor includes: a base, a stator iron core and at least two connecting pieces; each of the connecting pieces is connected to the base and the stator iron core respectively. The stator iron core is fixed in the base; the rigidity of each of the connecting pieces is adjustable, and the adjustment is realized by the external force acting on any one of the connecting pieces. In this solution, by adjusting the rigidity of the connecting piece of the motor by external force, the noise reduction processing of the motor can be realized, and the realization method is simpler.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a motor and a method for controlling the motor to reduce noise. Background technique [0002] Electromagnetic noise is one of the main noise sources of electric motors. The direct cause of electromagnetic noise is that when the motor is running, there are electromagnetic rotating force waves of a specific frequency. When the electromagnetic frequency of these force waves is the same as the mechanical frequency of the high-frequency vibrating stator core, high-frequency electromagnetic resonance is generated, resulting in electromagnetic The noise is too high. [0003] At present, the stator core of the motor and its base are usually welded. For the current motor, when the motor has high-frequency electromagnetic resonance and the electromagnetic noise is too high, it is necessary to disassemble the motor, redesign the electromagnetic scheme of the motor to change...
